Ashtech Introduces ProFlex 500 CORS

ProFlex 500 CORS is a Continuously Operating Reference Station (CORS) designed to collect, store and transmit high quality GNSS data for multiple applications, including a CORS and a field campaign receiver, for either post-processed or RTK applications.

Istanbul, Turkey – Ashtech, at the
INTERGEO EAST conference, introduced the ProFlex 500 CORS, an advanced,
multifunctional Continuously Operating Reference Station (CORS) designed to
collect, store and transmit high quality GNSS data for multiple applications,
including a CORS and a field campaign receiver, for either post-processed or
RTK applications.

According
to Olivier Casabianca, product marketing manager: “Ashtech has a strong and
natural legacy in manufacturing reference stations. Today, we simply introduce
the best ever Ashtech reference station.” The superiority of ProFlex 500 CORS begins
with Ashtech’s BLADE signal processing technology enabling it to provide
the highest quality GNSS raw data using measurements from three constellations,
GPS, GLONASS and SBAS. It offers
an easy to configure web server interface, instant real-time multi-data
streaming, full meteorological and tilt sensors support, and fully integrated
communications, including Ethernet, GSM/GPRS, UHF radio and Bluetooth.

Advanced CORS Features

Programming
sessions allows users to retrieve any stored GNSS, meteorological and tilt
sensor data, while a ring file memory ensures the most recent data are always
available. The embedded FTP server permits
the administrator to perform maintenance steps remotely and allows authorized
users to download raw data files directly from the receiver. Users can choose
to automatically use FTP push to securely upload data files or the embedded FTP
server to manually retrieve data. Conversion to RINEX employs Hatanaka
compression, and the internal memory can easily be expanded through the
addition of USB flash or external hard drives.

Advanced GNSS
Features

The
ProFlex 500 CORS has been extensively tuned to provide the highest quality raw
data and specific observation masks to ensure the perfect synthesis, specific
to each application, between quality and availability. The BLADE technology
ideally matches data to application as a full CORS or campaign receiver for
either post-processing or RTK applications.
In addition to delivering raw data files in Ashtech Optimized Messaging
(ATOM) or Rinex format, the ProFlex 500 CORS can simultaneously deliver
real-time RTK corrections in ATOM, RTCM 2.3 & 3.0 & 3.1 or CMR &
CMR+ format in multiple ways, including Direct IP, NTRIP server, radio, GSM
modem, Ethernet data streaming as a server or a client with up to 9 virtual IP
ports available, each with a specific data format.

Flexible and
Rugged Campaign Receiver

The ProFlex 500 CORS has equal utility as either a field
campaign receiver or a portable or permanent base station for either post-processed
or RTK applications. Rugged and IP67 rated, the
receiver is made to withstand harsh environments, and it also includes an
internal removable battery, which acts as a built-in uninterruptible power
supply. The ProFlex 500 CORS can
either just collect and store raw data or it can simultaneously collect, store
and broadcast RTK corrections. The receiver’s instant multi-data streaming
capability enables easy access to RTK corrections for real-time centimeter
accurate surveying and mapping applications. Enhanced Ethernet connectivity
provides NTRIP and Direct IP capabilities enabling users to build their own
DGPS and/or RTK corrections server without any additional software or
equipment.

Advanced Web
Server uses Web 2.0

The ProFlex 500 embedded and password-protected
web server provides full remote control via an internet connection. The
generation of raw data files organized as sessions are entirely manageable
through the web server, with preset duration permitting 24/7 data recording.
The embedded ring file memory function offers virtually unlimited storage. When
this function is enabled, it allows the oldest files in memory to be
automatically deleted, if necessary, to provide storage space for current files
being recorded. The ring file buffer function permits raw data recording
simultaneously with data recording performed through the programmed sessions.
Settings such as site name, recording elevation mask, recording interval, etc.
can be different from those found for sessions. For example, raw data can be
collected at 1 Hz through sessions while those collected through the ring file
buffer function may be at 20 Hz. Raw
data files and meteorological and tilt data can be pushed automatically to an
external FTP server. For quick responses to a triggered alarm, ProFlex 500 CORS
administrators can choose to be informed via email if possible malfunctions are
detected by the receiver.

Events

The Salina Seminar Series combines top notch speakers and a wide variety of topics with the opportunity to network with leading vendors and Land Surveyors from all over the Midwest, creating one of the premiere educational venues in the Midwest.

Annually, TSPS produces a two-day, multi-track, affordable and accessible educational event designed to provide continuing adult education and credit hours approved by the Texas Board of Professional Land Surveyors to the community of professional surveyors as well as other professionals.

Products

We began by creating a survey as a cooperative effort between several high level geospatial leaders, POB staff, and Clear Seas Research market research experts. The survey was sent out to more than 25,000 geospatial professionals who subscribe to POB and/or are members of MAPPS.
